Welcome to Project 20 - Smartphone Medical Device Hub

44X Senior project

1 Project Overview
In today's society we rely heavily on modern technology to go about our daily lives; from protecting our youth to adding quality to our standard of living. Technology is becoming more embedded in our lives providing us with data and information exchange that serves many different facets of life. This project will bridge the gap between medical data and daily applications.

This project is the first step to improving data for those suffering with diabetes while also unifying their sources of data into one easily accessible place like their smartphone. Integrating this data into such an application will lead the way to more accurate and safe data for users. Imagine, checking your blood glucose while at work, the gym, or school with your smartphone and then be able to group that information with suggested foods to help you plan your day.

This project is to create a proof-of-concept of a 'hub' that allows for attachment of specialty devices (including, but not limited to, medical devices) to a current generation of smartphones (iPhone, Android, etc.). At a minimum the device must be able to measure blood glucose levels and upload information to the smartphone. Also, using the same technology, there must be one other device that can use the 'hub' to connect to a smartphone. The final goal is to embed circuitry and specialty connectors into a phone case that has the capabilities to take measurements as well as make connections to specialty devices and transmit the information to a smartphone wirelessly. This would allow for a central device in modern life to easily measure and monitor blood glucose levels for Diabetics as well as allow for connections with other devices tailored to making the smartphone more accessible and useful.

Throughout our history, technology has served as the fundamental building blocks to our survival and development. From the first map to the first navigation system, we have been able to add data exchange into our daily lives and move on to the next revolutionary frontier. This new system will add that factor to those living with diabetes while having the potential to one day help many others suffering from different diseases.

The basic needs for our project after consulting with our mentor are:

*Blood Glucose Meter: The device must have the capability to quickly and accurately measure blood glucose levels by only using a reasonable sample size.

*Case: Modern products, like smartphones, have sleek cases that are easy to use and look stylish. Current products have to match their styles in order to compete in the market today. The customer will want something modern, easy to store, durable and light to carry.

*Conserves Power: The device must not waste power when not in use. Customers will save time and money by having a product that will conserve power in between uses.

*Rechargeable: The customer will need to be able to easily recharge the device. Having a rechargeable battery will increase the portability of the device. The customer will save money by using a rechargeable battery instead of consistently buying standard batteries.

*Self Powered: The device must be capable of making measurements without being connected to the smartphone. The customer might not have their smartphone at the time that they take their blood glucose measurements, therefore the device should be able to work properly without the presence of a smartphone.

*Software: There needs to be a method to at least track blood glucose measurements and store them on a smartphone for further review. The measurements for customers will be more useful if they can track their individual measurements and be able to access them later on. The device will be convenient for customers to bring to doctor appointments.

*Wireless: The device must be easily accessible to the smartphone. Customers will find it convenient to have their glucose meter be able to connect and store information on their personal phone. A wireless connection will provide easy uploading without storing and using extra wires.

*PCB: The device needs to be about the same size as a smartphone. The device also needs to be easily replicated. The best way to accomplish this is to custom make a printed circuit board.

*Indicator Light: The device should be able to indicate that it is working without the user having to look at the smartphone. The best way to do this will be with an indicator light.
